Chernobyl - What Have We Learned? : The Successes and Failures to Mitigate Water Contamination Over 20 Years
Twenty million people have been exposed to Chernobyl radionuclides through the Dnieper River aquatic pathways. This book presents a 20-year historical overview and comprehensive study results of the aquatic environment affected by the 1986 Chernobyl nuclear accident. During this time, many water quality management practices and countermeasures were enacted. The book presents in-depth analyses of these water remediation actions, using current science and mathematical modeling, and discusses why some were successful, but many others failed. The chapter entitled Where Do We Go From Here? incorporates a comprehensive discussion of the planned New Safe Confinement (NSC) structure to cover the Chernobyl plant. The book closes with a summary and conclusions drawn from these analyses, making it a valuable reference tool for the future. This book will be of interest to engineers, scientists, decision-makers, and those involved in radiation protection and radioecology, environmental protection and risk assessment, water remediation and mitigation measures, and radioactive waste disposal. In addition, the detailed, almost day-to-day, emergency responses to the Chernobyl accident described in this book will also be useful to people developing emergency and long-term responses to accidental or intentional (by terrorists) releases of radionuclides, toxic chemicals and biological agents.

In turn, subsequent chapters focus on protecting the fetus and neonatal management regarding chemotherapy for leukemia in pregnancy, including the treatment and risks for the fetus (for each type of leukemia), intrathecal therapy and its effects on the fetus; supportive drugs, antibiotics and antifungals for pregnant patients during chemotherapy, including intervention and dose adjustments; palliative care for women with leukemia in pregnancy; breastfeeding during treatment for leukemia; pharmacological aspects of supplements, vitamins and nutrition in pregnancy during leukemia treatment; and more.
Chemokines and Viral Infection
This edition of Current Topics in Microbiology and Immunology examines the role of chemokines and chemokine receptors in host defense and disease development following viral infection. Chemokines represent a family of over 40 small proteins that, for the most part, are secreted into the environment and function by binding to G protein-coupled receptors (GPCRs) that are expressed on numerous different cell types. When initially identified close to 30 years ago, these molecules were associated with various human inflammatory diseases and it was recognized that expression may be integral in leukocyte recruitment to inflamed tissue. There are now four sub-families of chemokines identified based on defined structural criteria relating to the positional location of conserved cysteine residues within the amino-terminus of the protein. Chemokines are now recognized as important in numerous biological processes ranging from maintaining the organizational integrity of secondary lymphoid tissue to participating in various aspects of both innate and adaptive immune responses following microbial infection. With this in mind, this book highlights the functional roles of chemokines and their receptors in participating in various aspects of the immune response against well-known viral pathogens.

Challenging American Leadership : Impact of National Quality on Risk of Losing Leadership
After leading the world during most of the 20th century in economic, political, technological, military, and even social terms, America’s role is now being challenged. Its values questioned, and its methods often disparaged, America had become the clear example to be followed or even copied, yet its more recent strategic and political decisions gained little international support and a lot of outright opposition. The quality of its national planning and decision making has been severely compromised, and risk management appears to be largely absent. India and China are now emerging as new economic powers, with advancing technological prowess. Their focus is on socioeconomic development, but their capabilities and potentials are much broader and may challenge America's leadership before long, unless it recognizes the changing demands of the new wide open globalized world.

Challenge In biologic drug delivery
Biologics are currently one of the most promising avenues for therapeutic interventions in conditions such as metabolic disease, ageing and inflammatory disorders, and for chronic ailments, oral delivery of such medicines has for years been recognised as an important goal. Despite decades of intensive research, oral delivery of biologics is only just starting to prove feasible. There has been much talk about the barriers to uptake of biologics, and indeed, one function of the intestine is to prevent, in one way or another, passage of unwanted materials across the gut, and yet, grams of biological agents both large and small pass across the intestinal cell wall every day. This review first describes the functioning of the gut under normal circumstances, then identifies the principle biological mechanisms, which have been harnessed successfully, to date, to achieve oral uptake, outlining the pros and cons of each approach.
Certification and security in inter-organizational E-services ; IFIP 18th World Computer Congress, August 22-27, 2004, Toulouse, France
This collection of papers offers real-life application experiences, research results and methodological proposals of direct interest to systems experts and users in governmental, industrial and academic communities. This book also documents several important developments. The uptake of distributed computational infrastructure oriented to service provision, like Web-Services and Grid, is making C&S even more important. E-services based on legacy systems managed by autonomous and independent organizations, a common situation in the public administration sector, increase overall complexity. The increased presence and use of e-service IT-infrastructures depends on the critical ability required for all security issues, from the basic (availability, authentication, integrity, confidentiality) to the more complex (e.g. authorization, non-repudiation).
Cephalopods Present and Past : New Insights and Fresh Perspectives
Cephalopods are diverse, highly developed molluscs capable of swimming and jet propulsion. These animals are an important component of present-day marine ecos- tems throughout the world and comprise approximately 900 species. They also have an extraordinary fossil record, extending back to the Cambrian Period, with as many as 10,000 extinct species. Throughout their long history, they have experienced sp- tacular radiations and near-total extinctions. Because of their superb fossil record, they also serve as ideal index fossils to subdivide geologic time. This book touches on many of these themes, and it treats both fossil and present-day cephalopods.
